Officina Stellare


Diffraction-limited over a wide and flat field, the RiFast design will push any camera to its limits... and will do it FAST! The extraordinary f/ ratio allows a higher productivity per night, a significant factor for surveys, SN search, asteroid control, and many other fields of modern astronomy.

The central obstruction is about 50%, but still smaller than similar designs, that simply can't compete under any point of view. The visual contrast is very good, thanks also to the special ultra-dark paints we use.

The corrector group is very close to the focal plane, so chromatic aberration is undetectable.
